Abstract

Die Erfindung betrifft ein Laufrad für eine hydraulische Strömungsmaschine nach Fancis-Bauart, insbesondere für eine Wasserturbine;
  • mit einem Laufradboden, einem Laufradkranz sowie einer Vielzahl von Schaufeln;
  • jede Schaufel weist eine Eintrittskante und eine Austrittskante auf;
  • die Austrittskante einer jeden Schaufel ist an einem Punkt im Bereich des Laufradbodens derart umgelenkt, daß der weitere Verlauf der Austrittskante auf den Laufradboden an einem Punkt auftritt, der gegenüber einem sich ohne Umlenkung der Austrittskante ergebenden Auftreffpunkt stromabwärts liegt.
